Stats for the total # blocks and blocks per DN
----------------------------------------------
Key: HDFS-2708
URL: https://issues.apache.org/jira/browse/HDFS-2708
Project: Hadoop HDFS
Issue Type: Improvement
Components: data-node, name-node
Reporter: Eli Collins
Priority: Minor
It would be useful for tools to be able to retrieve the total # blocks in the
file system (and also display eg via dfsadmin report, this is currently only
available via FSNamesystemMetrics, so would add to ClientProtocol#getStats?)
and the total number of blocks on each datanode (via DataNodeInfo).
